Linux Device Drivers 3rd Edition: A Comprehensive Guide for Kernel Programmers

Linux Device Drivers 3rd Edition is a book that covers the essentials of writing device drivers for the Linux kernel. It explains how to communicate with hardware devices, how to use kernel facilities, how to work with different types of devices, and how to handle concurrency and synchronization issues. The book also provides examples of device drivers for common devices such as serial ports, USB devices, network interfaces, and block devices.

The book is written by Jonathan Corbet, Alessandro Rubini, and Greg Kroah-Hartman, who are experienced kernel developers and maintainers. The book is based on the 2.6 Linux kernel, but it also covers compatibility issues with older and newer kernels. The book is available in PDF format for free from the official website[^1^], and it can also be converted to MOBI format using online tools or software.

Linux Device Drivers 3rd Edition is a valuable resource for anyone who wants to learn how to write device drivers for the Linux kernel. It covers both the theory and the practice of device driver development, and it provides useful tips and tricks along the way. Whether you are a beginner or an expert, this book will help you master the art of Linux device driver programming.

The book is divided into 17 chapters, each focusing on a specific aspect of device driver development. The first chapter introduces the Linux kernel and its architecture, and explains how to download, configure, build, and install it. The second chapter covers the basics of device drivers, such as modules, kobjects, sysfs, and device model. The third chapter deals with platform drivers and device tree, and shows how to describe hardware using device tree syntax. The fourth chapter explores the I2C and SPI buses, and how to write drivers for devices that use them. The fifth chapter discusses the concurrency and synchronization issues that arise in device driver development, and introduces various kernel mechanisms to handle them, such as spinlocks, mutexes, semaphores, atomic operations, and workqueues.

The sixth chapter explains the Linux kernel timekeeping mechanism and how to use time-related APIs, such as timers, hrtimers, ktime, and jiffies. The seventh chapter covers the regmap framework, which provides a generic way to access registers of hardware devices. The eighth chapter describes how to use DMA (Direct Memory Access) to offload CPU for memory copies between devices and memory. The ninth chapter introduces the GPIO (General Purpose Input/Output) subsystem, which allows controlling pins on a chip. The tenth chapter presents the IIO (Industrial Input/Output) subsystem, which provides support for sensors and actuators. The eleventh chapter explains how to write drivers for input devices, such as keyboards, mice, touchscreens, and joysticks.

The twelfth chapter covers the sound subsystem (ALSA), which provides support for audio devices and codecs. The thirteenth chapter discusses the video subsystem (V4L2), which provides support for cameras and video capture devices. The fourteenth chapter describes how to write drivers for network devices, such as Ethernet cards and wireless adapters. The fifteenth chapter explores the block device subsystem, which provides support for storage devices such as hard disks and flash drives. The sixteenth chapter deals with the character device subsystem, which provides support for serial ports and other miscellaneous devices. The seventeenth chapter concludes the book with some advanced topics, such as debugging techniques, tracing tools, testing methods, and kernel coding style. ec8f644aee
